Subject: How to restore $? AND $_ ?
Date: Wed, 24 Jul 2019 08:20:22 +0200	[thread overview]
Message-ID: <CAKc7PVDqisHHAcJK06TaFmxCmmhdbYWTQUeBRsfaYu=A8xgvXA@mail.gmail.com> (raw)

Hello,
consider the following:

sched-fun() {
    # UND=$_
    local ret=$?

    sched +1 "sched-fun \$_"

    # : $UND
    return $ret
}

The point is that the 2 commented lines must be run in the same place
as the next lines after them in order to work. No way out of this
problem? It is about not disrupting user session with background
tasks, I think that this is in general important.
